Metadata is not saved when modifying a barebones script

Hi,

I’m not sure if this is a bug or expected behavior but I find it a bit confusing.

If I create a barebones script (no notebook nor cell metadata):

# script.py with no metadata
1 + 1

Then open it with jupytext, add some metadata (e.g. add a tag) and save it. Metadata gets lots (and console does not show any warnings).

I think it’s because jupytext fails to recognize the format because if I start with a script with some metadata:

# + tags=["some_tag"]
1 + 1

And add more metadata (e.g. add another tag), the file updates correctly.

Hi @mwouts, thanks for the detailed answer.

Not adding metadata to all .py files make sense to avoid cluttering files. I’m thinking a console warning can help clarify why metadata is being removed when saving certain scripts (as the one from my example). Let think through this and I’ll come back with some feedback.

Awesome!

Is there any way to make the notebook view the default choice?

Not yet, sorry… If you want to follow that subject, you can subscribe to #271. But it’s not planned for the immediate future, as I don’t see exactly how to implement it 😃
